White smoke @ cold start.

im thinking either an injector bore did not get cleaned, a copper wasnt installed, or fell off upon install, or injector wasnt torqued. fuel slipping by the copper, trading off with compression. the seal will eventually blow out and cylinder will hydrolock. I'd recheck injectors...

this is what happens when we let a pump tech work on a truck... he didnt grease the copper and it fell off while putting injector into cylinder... it lasted for 2000 miles, then hydrolocked...

and the snail trail it left while driving into shop

I have not done this test to a 7.3 yet, but on 6.0's it works great....

engine cold, remove the fuel filter, top off the bowl with fuel, use a starter buttona nd jump the relay on the passenger side inner fender. spin the engine over for a few seconds and watch the fuel bowl for bubbles... if bubbls are present, your getting compression back through your injectors... disconnect one feed line to determine which bank is fubar... I personally would remove all injectors if this turns out to be the issue

Kinda what I was thinking. Just figured it was obrings.

OP.... If your oil level is good why do you think ur turbo is pumping oil?

I'll give that a shot and see what happens. My reasoning for the turbo idea is just past experience with heavy equipment. I've had one big truck, and a dozer do the same thing. It didn't use enough oil to notice change on the dip stick, but enough to smoke alot.

Sounds like it has a up pipe leak. I would pull the injectors and have a look. It's not that hard.

Looks like fuel in the pic but I'd also pull the intake and see if the turbo shaft has any play or if it looks like it's blowing oil.

I'd be willing to bet your o rings are shot. Fathers 96 did this. Fuel was leaking into.cylinders when it sat for a few hours.

Mine does the same thing. Put injectors in at 160K, almost 180K now, still does it before and after. (Injector o-rings should be seated by now) Not hard start just smokes til warm.
